Geophysics

Project to analyse the pattern of seismic anisotropy beneath the continent utilising data from temporary broadband networks deployed across Australia
Himalayan Model
Congested subduction happens whenever buoyant material such as an oceanic plateau gets caught up on a moving plate and eventually arrives at a subduction zone. The buoyant material may be scraped off or subducted, but it always puts up a fight which leaves characteristic scars on the over-riding plate.
The objective of this ARC Linkage project with Geoscience Australia and GSWA is to provide a compilation of 3-D models of the crustal and lithospheric structure from new broadband data obtained with deployment of 25 seismometers in Southwest WA.
The base of the Lake George fault scarp defines the edge of the basin and previous surveys suggested the Quaternary fault zone extends at depth. A dense seismic array of 100 nodal seismometers were deployed in late 2020 in the northern section of the basin and collected continuous seismic recordings for ~1 month
The lowermost mantle sits atop the core-mantle boundary – the most dramatic boundary within our planet, with contrasts in physical properties that exceed those that exist at the surface. Despite significant progress, this region is not well understood, and global seismology paves the path towards new understanding.

Imaging lithosphere structures of the Earth’s hidden continent, Zealandia

Zealandia, the Earth’s hidden continent submerged in the southwest Pacific Ocean, is the youngest and thinnest geological continent in the world. Yet, how this continent is formed remains to be further explored, mostly due to a poor understanding of its sub-surface structure.

Improving tsunami warning systems: fast and reliable estimation of source parameters of large earthquakes using long period W-phase data

This project uses state-of-the-art computational tools to calculate seismic waveforms for large tsunamigenic earthquakes. It will assess how critical is the effect of 3D seismic velocity structure in determining earthquake parameters like focal mechanism and rupture area, which are crucial for improved tsunami warning.
Moment tensors in seismology provide a theoretical framework to understand physical mechanisms of earthquakes (how they are generated in their source); in fact, apart from tectonic and volcanic earthquakes, the same framework is used to characterise explosions, landslides, meteorite impacts and other phenomena.
Distributed acoustic sensing (DAS), an emerging technology in solid Earth geophysics, provides new avenue to perform array seismology by transforming a single fibre-optic cable into a continuous sensing element which can collect broadband data at ~1 metre-spacing.
Earth’s internal structure and processes, which cannot be observed directly, must be inferred from data that can be collected at (or above) Earth’s surface. Our research in Mathematical Geophysics at ANU attempts to address the question of `How to do this?' `How robust are the results? '.
Pore-water within a basin flows in response to supply, extraction, topography, and imposed pressure gradients. Changes to these parameters in complex, tectonically active basins require complex, 3D, coupled models to understand. This project is concerned with developing, testing and applying such models.
Seismic imaging of the Earth's mantle
We wish to understand the Earth’s internal structure and processes, but we cannot observe these directly: everything must be inferred from data that can be collected at (or above) Earth’s surface. This project explores novel mathematical and computational methods for solving these challenging problems.
Mantle convection is the `engine' that drives our dynamic Earth. It is the principal control on Earth's thermal, chemical and tectonic evolution. The mantle transition zone plays a critical role in this fundamental process, by controlling the passage of material between Earth's upper and lower mantle.
Subduction zones are the most prolific producers of seismic and volcanic activity on Earth, yet many aspects of the subduction factory remain poorly understood. Surrounded by plate boundaries Australia has a unique advantageous location for recording earthquakes originating from nearby subduction zones.
Plate tectonics is the surface expression of a cooling Earth and convection in the Earth’s interior. Constraining the patterns of convective mantle flow is therefore important for understanding the dynamics of our planet and how the surface of the Earth evolves through time. Most of our inferences about mantle flow...
The Earth’s inner core is a planet within a planet: a hot sphere with a mass of one hundred quintillion tons of iron and nickel that lies about 5150 kilometres beneath our feet, still waiting to be discovered. Modern global seismology serves as an inverted telescope with which we can probe the Earth's deepest shell.

Palaeoenvironments

Magnetic minerals are almost ubiquitous in nature, which means magnetic techniques can be used to understand Earth’s magnetic field and deep-Earth dynamo processes, and act as proxies for system processes in palaeoclimate, paleoceanography, pollution tracing, and archaeology.
Research supports The group has funding to support one highly motivated PhD student, based on competition of applicants (academic background, research ideas, etc). Contact me if you are interested. We also welcome candidates who can raise fund (e.g., China Scholarship Council,...
Antarctic Coast Bathymetry in the region of Cape Darnley
This Geoscience Australia supported project is focused on a little known region of the East Antarctic coast, Cape Darnley. The aim is to assist with refining future coring locations using all previously collected Geoscience Australia geophysical data placed in context to recently reviewed bathymetric data.
“Lake George, an unsurpassed natural archive” is an ARC Linkage project, began in February 2015. The project is multidisciplinary, looking at the structural, sedimentological, hydrogeological, archaeological, and landscape evolution history...
